The ISS Kit, otherwise known as the Incarnate System Study Kit, is a pseudo-Enhanced Armament developed by the Acceleration Research Society. Those who use it are called ISS Kit Users. Template:Spoiler
Background and Description
The ISS Kit is a mass-produced item that allows a Burst Linker to use two Incarnate abilities, Dark Blow and Dark Shot, with little effort. It was created by a copy of Red Rider's memories and distributed into the Unlimited Neutral Field, and, like the rest of Red Rider's created items, it features his dual gun emblem on the item icon.
Magenta Scissors, likely a member of the Acceleration Research Society, distributed many of these items to various Duel Avatars. If a Duel Avatar is unwilling to accept it, she injects it into his or her body by force. Examples of this are Mint Mitten and Plum Diver of Petit Pacquet, Ash Roller, and Cyan Pile, who sought it out for himself.
Its purpose is to feed on the negative energy collected by the Burst Linkers using it and transport it back to a main body. The ISS Kit Main Body is a large mass of flesh, blood vessels, and a single large eyeball that resides in the upper levels of Tokyo Midtown Tower. When Silver Crow and Lime Bell accidentally traveled into Brain Burst's main server, they saw it as a giant black mass covering up the infinite starscape behind it. Many Duel Avatars, all of which had the kit, could also be seen walking to it like zombies. Crow and Bell, with a copy of Saffron Blossom's memories, manage to damage it enough for Cyan Pile to break free of its spell.
The master plan of the Acceleration Research Society was to use the dark energy it collected in tandem with Scarlet Rain's Enhanced Armaments and the artificially-created metal-color Wolfram Cerberus in order to create a second Calamity Armor. However, the ISS Kit Main Body is destroyed by Black Lotus, Sky Raker, Aqua Current, and Ardor Maiden before it gathers enough energy, leading to the Calamity Armor Mk-II's eventual defeat at the hands of Nega Nebulus and Metatron.
As it died, the ISS Kit Main Body was revealed to have actually been a Burst Linker that had no points left. In addition, the ghost of Red Rider, which had appeared to fight Black Lotus and the Elements, had promised to deactivate the ISS Kits when the main body was destroyed, and he kept the promise, releasing all the other ISS Kit Users.
The ISS Kit grants its user two different Incarnate abilities, both powered by the user's negative emotions.
- Dark Blow - a powerful close range attack
- Dark Shot - a powerful long range attack
Because they are Incarnate attacks, they cannot be defended by normal means. However, Nega Nebulus was easily able to defeat a numerically superior team of ISS Kit Users by countering it with stronger Incarnate attacks.
Before the ISS Kit's main body was destroyed, a great number of ISS Kit Users were confirmed.
